A Hybrid Transmitting Coil for Angular-Freedom Wireless Power Transfer

open access: yes, 2023
<p>This letter presents a hybrid transmitting coil (HBRTx) for angular-freedom wireless power transfer. The rotating magnetic field is analyzed and obtained in different charging planes by three coil configurations to adapt the Rx rotations. Furthermore, the CLC (capacitor-inductor-capacitor) impedance matching networks (IMN) are implemented on ...

Tuning of a wireless power transfer system with a hybrid capacitor array

open access: yesWireless Power Transfer, 2016
Power transfer efficiency in loosely coupled inductive systems can be enhanced by resonance. Primary and secondary can be tuned to same resonant frequency. In this paper, MOSFET-based Varactors and switchable capacitors are used for re-tuning of such a system at 13.56 MHz.
